本研究以月桂Skimmia laureola叶水提物为原料，在室温下制备了银纳米粒子（AgNPs）。在合成过程中观察到反应混合物的颜色变化（浅黄色至深棕色）。生物合成的银纳米颗粒在460 nm左右显示出表面等离子体共振。通过SEM和XRD分析证实了银纳米粒子的球形和六方结构以及晶体性质。研究表明，大叶黄杨叶提取物中的活性成分主要为黄酮类化合物。月桂醇类化合物如三萜类化合物、茵芋二醇和香豆素主要参与银纳米颗粒的合成。此外，还研究了S.月桂叶和生物合成的银纳米颗粒被发现是对抗测试的人类病原体的有效试剂，并且其是用于生物医学应用的合适的纳米材料。(C)2015 Elsevier B.V.版权所有。
In the present study, silver nanoparticles (AgNPs) were synthesized by using aqueous leaves extract of Skimmia laureola at room temperature. The color change in reaction mixture (pale yellow to dark brown) was observed during synthesis process. Biosynthesized silver nanoparticles showed surface Plasmon resonance at around 460 nm. The spherical and hexagonal shapes and crystalline nature of silver nanoparticles were confirmed by SEM and XRD analysis. The bioactive chemicals constituent of leaf extract of S. laureola such as tritepenoids, skimmidiol and coumarins, were mainly involved in the synthesis of silver nanoparticles. Furthermore, antibacterial potential of aqueous extract of S. laureola leaf and biosynthesized silver nanoparticles found to be potent agent against tested human pathogens and it is suitable nanomaterial for biomedical application.
